“…The mandibular canal (MC) is a hollow space that carries the inferior alveolar neurovascular bundle, which innervates and provides blood supply to the gingiva, teeth, and rostral soft tissue of the mandible ( 1 , 2 ). In the dog, the MC begins at the mandibular foramen located at the ventral region of the temporalis muscle insertion on the medial aspect of the ramus of the mandible.…”

“…In the dog, the MC begins at the mandibular foramen located at the ventral region of the temporalis muscle insertion on the medial aspect of the ramus of the mandible. The inferior alveolar neurovascular bundle runs rostrally through the MC from the mandibular foramen to its end at the distal, middle, and rostral mental foramina on the buccal surface of the mandible at the level of the second premolar and canine teeth ( 1 , 3 ). Knowledge of the MC's position regarding the mandibular teeth is of paramount importance since iatrogenic trauma of the inferior alveolar neurovascular bundle during dentoalveolar surgical procedures has been associated with intraoperative hemorrhage and temporary or permanent postoperative paresthesia or pain ( 4 , 5 ).…”

The intimate relationship between the mandibular canal (MC) and the first mandibular molar tooth presents challenges when performing dentoalveolar surgical procedures due to the probability of causing iatrogenic injury to the inferior alveolar neurovascular bundle. Superimposition between the MC and the first molar (M1) tooth roots is often observed on intraoral dental radiographs in small breed dogs. However, due to the radiograph's bidimensional nature, it is impossible to determine the buccal or lingual localization of the first molar roots with respect to the MC. Thus, this study's objective was to determine the localization of the first molar tooth's roots in relation to the position of the MC and their overlapping percentage with the canal in small-bodyweight dogs (<15 kg) using tomographic diagnostic images. For this, cone-beam computed tomography and high-definition computed tomography exams from 103 small breed dogs (under 15 kg) were retrospectively assessed to determine the lingual or buccal localization of the first molar tooth's roots with respect to the MC and the degree of overlap of the roots with the canal. In conclusion, most of the roots of M1 of dogs under 15 kg were located at the MC's lingual aspect (82.7%) with an overall superimposition median with the MC of 100 and 90% for the mesial and distal roots, respectively. Straddle tooth roots were not a common anatomical presentation in the dogs of this study.

“…5 However, even when attachment loss has occurred, careful debridement procedures can prevent further bone loss and, in some cases, achieve reattachment. 9 The detailed steps for dental cleaning and periodontal therapy have been described and were updated in the 2019 AAHA Dental Care Guidelines for Dogs and Cats. 60 This protocol is considered standard of care for basic periodontal management and is performed under general anesthesia.…”

“…Several types of flaps for open approaches to debriding furcation lesions have been described; one that has been described in both the human and veterinary literature is the modified Widman flap. 9,71–73 When the flap has been created and the tissues are elevated, the tooth roots and furcation areas are exposed for debridement under direct visualization. Instrumentation at the furcation with the open flap approach is similar to instrumentation with the closed approach.…”

“…2 In some cases, selection of which root to remove may need to be decided intraoperatively, 81 although every attempt should be made to determine this preoperatively. 2 Hemisection or trisection may be indicated if an advanced furcation lesion or lesions are present but all roots are individually periodontally healthy, 1,2,9,76 allowing for retention of the separated tooth roots. Again, root shape and interradicular dimensions are important considerations.…”

The furcation is the anatomic area where the roots divide on a multirooted tooth. Periodontal disease causing alveolar bone loss can lead to furcation lesions of various stages. Once furcation involvement has occurred, the area can be more difficult to clean or treat due to the complex anatomy and morphology of furcations. Teeth with short root trunks, longer tooth roots, and roots with wide furcation entrance areas/degrees of separation and wide root divergence are considered better candidates for long term maintenance. Dog teeth possess many of these advantageous anatomic features compared to human teeth. Treatment options for teeth with furcation lesions include: closed debridement, open debridement, furcation plasty, tunneling, partial tooth or root resection, root separation (hemisection or trisection), regenerative therapies, or exodontia. There are many factors to consider in determining treatment options. The favorable and unfavorable characteristics for maintenance of teeth with furcation lesions are summarized. Home care and ongoing professional care are important aspects of periodontal disease control for any patient. Studies of systemic and local antibiotic therapies in human patients have not demonstrated reduction of furcation stages, and probiotic effects at furcation sites have not been specifically examined. Human review studies show that most molar teeth once deemed “hopeless” due to stage 3 furcation lesions can be maintained for at least 5 to 15 years with supportive periodontal therapy. Similar long term studies in dogs are needed to improve the evidence-based management of canine patients with furcation lesions.
